DISCONNEC'IING SYVITCH AND SUPPORTING Iw-IEANS THEREFOR.

Application filed April 12, 1921.

My invention relates to disconnecting switches and supporting means therefor, and more particularly to disconnecting switches of the tection-insulator type, in combination .vith a supporting member that serves as both a hanger and a strain insulator.

One object oi my invention is to combine, in simplified form, a disconnecting, or section break, switch and supporting means therefor.

A further object is the provision oi a hanger for transmission line that serves also as a strain insulator.

Heretoi ore, supporting members for transmission lines have been constructed in such manner that they serve merely as hangers, and disconnecting or section break switches have required expensive and comparatively complicated supporting appara tus. By my invention, I provide a single structure that serves as a switch-supporting apparatus, a strain insulating apparatus and hanger.

Briefly stated, my invention comprises ordinary strain or suspension insulators assembled in triangular form, with a disc0nnecting switch disposed along the base there d a hanger at the apex thereoi for conthe apparatus to a pole or tower, pective adjacent ends of the transline being connected to the insulating members adjacent to the lcwer corner oi the triangle.

The single figure of the drawing illustrates a portion of a transmission line and a supporting tower with my invention applied thereto.

The adjacent ends, 1 and 2, of a transmission line are supported from a tower 3 by means of a hanger 1-, through a threeway connecting member 5, strain insulators 6 and 7 and connecting members 8 and 9.

The conductor ends 1 and 2 are securely attached to the connecting members 9 and 8, respectively, and connecting members is and 9 are prevented from spreading apart by means of strain insulators 10. The insulators 6. l and 10 are composed of separate insul .ing members in the manner common to strain or suspension insulators of this general type.

The connecting members, 8 and-9 are of suitable conducting material and are pro- Serial No. 460,619.

'ided with a hinge contact member 11 and a contact jaw member 12 respectively. switch blade 13 is pivotally connected to the hinge member 11 and is adapted to be latched into engagement with the contact member 12 by means of the pivoted latch member 14 that is maintained in opm'ntive position by a spring 15.

As is well known, transmission lines are maintained under high mechanical tension, 0 strain, in order to prevent undue sag sing points intermediate their supports, and, in the construction illustrated, a supporting structure of considerable strength is provided to maintain the ends 1 and 2 in their proper relative positions. Ordina- "ily a strain insulator, such as the member 10 employed as a tie member. In this case, instead of providing a single vertical l y disposed hanger for supporting the transmission line at the proper height, the members 6 and 7 serve not only as suspension members but also, by reason of their run gular disposition, as strain members to assist the strain member 10 in maintaining the ends 1 and 2 in their proper relative positions.

It will be apparent that the members 6 and 7 serve also to reduce the tendency of the switch parts to sway when the switch is being ope "ated and to maintain the parts of the switch in proper alignment. This is an advantage not found in aconstruction that employs a single vertical hanger.

The switch blade 13 is operated by means of a hook-stick that may be inserted into the opening 16 in the latch 14, as is common in disconnecting switches mounted at considerable distances above the ground.

The structure is susceptible oi various changes. F or instance, two strain members 10, may be employed in sideby-side relation and the switchblade member mounted therebetween. Various other modifications may be made without departing from the spirit of the invention as defined in the accompanying claims.

I claim as my invention:

1. In a section switch, the combination with a switch blade, of supporting means for the switch, comprising three triangularly arranged supporting members, one of which is in substantial parallelism with the switch blade, and a hanger member connected to the adjacent ends of the other two supporting members.

2. In a section switch, the combination with a switch blade, of supporting means for the switch, comprising three triangularly arranged supporting members, one of which is in substantial parallelism with the switch blade, and a hanger member connected to the adjacent ends of the other two supporting members, and means adjacent to the ends of the first named supporting member for supporting the respective ends of the switch blade.

3. In a transmission line, the combination or" two relatively angularly disposed hanger members having their adjacent ends connected to a support, a positioning member "for maintaining their other ends in properly spaced relation, and means for attaching the other ends of the hanger members to adjacent sections of the transmission line.

4. in a transmission line, the combination with a hanger therefor provided with oppositely disposed supporting members each connected to the other at one end, of means for maintaining their other ends against relative displacement. I

5. In a transmission line, the combination with a hanger therefor provided with oppositely disposed supporting members each connected to the other at one end, of means for maintaining their other ends against relative displacement, and means for attaching adjacent portions or the transmission line to said other ends.

6. A disconnecting switch comprising, in combination, a hinge contact member, a bridging member having one of its ends pivotally supported by the hinge member, a stationary contact member adapted to be engaged by the free end of the bridging member, means for supporting the contact members comprising a pair of hanger members each of which has an end connected to the respective contact members and its other end connected to a common supporting member, and means for maintaining the first named ends of the hanger members in properly spaced positions.

7. A combined strain insulator and hanger comprising three triangularly arranged insulating members connected at the apex to a hanger and provided adjacent to its base corners with means for attaching portions of a transmission line thereto.

In testimony whereof, I have hereunto subscribed my name this 31st day of March,
